Have been playing with an Epilog Laser Engraver and Corel DRAW, the
recomended by Epilog, graphics software. the "3D mode" uses the gray
scale in the image you provide to determine "depth of burn" - white
meaning do not burn at all, black meaning burn to max depth and grays in
between determining depth of cut/burn.

Created some gray scale images in PhotoShop, imported them to Corel Draw
X3 on the PC that sends data to the laser via a "printer driver" and
have run some test samples on mainly flat pieces of redwood, maple,
poplar and what may be honey locust. Last laser session was working on
curved surfaces on 2 intersecting arcs walnut samples.

Looks like I'll be able to use the laser to "carve" on curved pieces,
held in a chuck attached to a shop made jig.

Have put up two pages on what I've found - with pictures.
